Lantana camera plant named ‘UF-T4’

ABSTRACT

A new and distinct cultivar of  Lantana camara  plant named ‘UF-T4’, characterized by its moderate vigor, mounding growth habit, free flowering, bright yellow/magenta flower color, little fruiting, high level of female sterility, high level of male sterility, and not hybridizing with  Lantana depressa , is disclosed.

Latin name of the genus and species of the plant claimed: Lantana camara L. (Lantana strigocamara R. W. Sanders).

Variety denomination: ‘UF-T4’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of lantana, botanically known as Lantana camara, and hereinafter referred to by the name ‘UF-T4’.

Lantana camara is a member of Verbenaceae. Plants of this species attract numerous species of butterflies, tolerate harsh environmental conditions, have low maintenance requirements, and are easy to grow, making L. camara highly desirable for use in containers, hanging baskets, and landscapes. Commercial production of L. camara is widespread in the nursery industry, especially in the southern United States. However, this species has escaped cultivation through seed dispersal and has hybridized (as pollen donors) with Lantana depressa, a rare species native to Florida, resulting in its classification as a Category I invasive species for South and Central Florida. Very few of the existing commercial L. camara cultivars are highly male- and female-sterile. Therefore, there has been a strong need for new sterile cultivars in L. camara.

‘UF-T4’ is a product of a planned breeding program at the University of Florida. The primary objective of the breeding program is to create new sterile lantana cultivars with attractive plant growth habits (mounding, semi-mounding, to spreading), freely-flowering, and attractive flower coloration.

The new lantana originates from a planned cross between ‘Carlos’ (unpatented) and a proprietary breeding line LAOP-9. ‘Carlos’ was selected as the female parent for its tetraploidy level, bright pink/magenta flower color, and lack of production of female gametes. Breeding line LAOP-9 was selected out of a population of progeny from open pollinated ‘Lola’ (unpatented) in Wimauma, Fla. It was used as the male parent in the stated cross for its diploidy level, compact growth habit, and lack of production of unreduced female gametes. The stated cross was made in March 2007 in Wimauma, Fla. ‘UF-T4’ was discovered and selected in Wimauma, Fla. in October 2008 as one flowering plant within the progeny of the stated cross.

Asexual propagation of the new lantana by vegetative cuttings in a controlled environment in Wimauma, Fla. since 2008 has shown that the unique features of this new lantana are stable and reproduce true to type in successive generations.

BRIEF SUMMARY OF THE INVENTION

The cultivar ‘UF-T4’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature and light intensity without any change in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘UF-T4’. These characteristics in combination distinguish ‘UF-T4’ as a new and distinct cultivar of Lantana: 1) Moderate plant vigor; 2) Mounding and outwardly spreading growth habit; 3) Light green-colored leaves; 4) Freely flowering habit; 5) Yellow and magenta-colored flowers; 6) Little fruiting and no or few berries; 7) High level of female sterility; 8) High level of male sterility; and 9) Little hybridization potential with Lantana depressa.

Plants of the new cultivar differ from plants of the female parent, the cultivar Carlos, in the following characteristics: 1) Plants of the new cultivar are triploids, while plants of ‘Carlos’ are tetraploids; 2) Plants of the new cultivar are mounding and outwardly spreading, while plants of ‘Carlos’ are more upright; 3) Flowers of the new cultivar are yellow-colored when initially open and turn magenta when matured, while flowers of ‘Carlos’ are pink/magenta-colored; 4) Plants of the new cultivar produce no or few fruit and are highly female-sterile, while plants of ‘Carlos’ are female-fertile and produce more fruit; and 5) Plants of the new cultivar have low pollen stainability or viability, while plants of ‘Carlos’ have much higher pollen stainability or viability.

Plants of the new cultivar differ from plants of the male parent, the breeding line LAOP-9, in the following characteristics: 1) Plants of the new cultivar are triploids while plants of LAOP-9 are diploids; 2) Plants of the new cultivar are mounding and outwardly spreading, while plants of LAOP-9 are more upright; 3) Flowers of the new cultivar are yellow-colored when initially open and turn magenta when matured, while flowers of LAOP-9 are yellow-colored; 4) Plants of the new cultivar produce no or few fruit and are highly female-sterile, while plants of LAOP-9 are female-fertile and produce more fruit; and 5) Plants of the new cultivar have low pollen stainability or viability, while plants of LAOP-9 have much higher pollen stainability or viability.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1986 Edition, except where general terms of ordinary dictionary significance are used. Plants used for the description were grown in the summer of 2011 in Wimauma, Fla. for 3 months from when terminal cuttings were made. Plants were planted in a 10.2-cm container and only trimmed minimally as needed at this time. Plants were grown outdoors for 3 weeks in early September in Wimauma, Fla. before flower color descriptions were done. During the production of the plants in the polypropylene-covered shadehouse, temperatures ranged from about 20.5° C. to about 36.1° C.

ASSESSMENT OF FEMALE FERTILITY

Four experiments were conducted simultaneously at the Indian River Research and Education Center (IRREC) in Ft. Pierce, Fla. (southeast Florida, USDA hardiness zone 10, and AHS heat zone 9-10), at the GCREC in Balm, Fla. (southwest Florida, USDA hardiness zone 9A, and AHS heat zone 10), at the Plant Science Research and Education Unit (PSREU) in Citra, Fla. (northern Florida, USDA hardiness zone 8B, and AHS heat zone 10), and at the North Florida Research and Education Center (NFREC) in Quincy, Fla. (northern Florida, USDA hardiness zone 8B, and AHS heat zone 9). The four experiment sites are located in three different hardiness zones (10, 9A, and 8B) and two different heat zones (10 and 9) (American Horticultural Society, 1998; National Gardening Association, 2011). The experimental design used in Ft. Pierce and Balm was a randomized complete block with three blocks. The distance between field blocks were at least 50 feet. Each plot within the block at these two sites consisted of two plants for each cultivar and one L. depressa plant (mixed planting of triploids and native lantana). The spacing between plants within each plot was 6 feet. The same experimental design and the same number of blocks were used in Quincy and Citra, except that L. depressa plants were not installed between triploid plants (pure planting of triploid plants). L. depressa does not occur naturally in north Florida. At each experimental site, ‘Pink Caprice’ was included as a control. It is commercially produced and very prolific in fruit (and seed) production. ‘Pink Caprice’ was planted at least 150 feet away from ‘UF-T4’.

Every four weeks beginning on late July 2009 until mid-December 2009, 20 peduncles (flower or fruit clusters) were harvested randomly from each of the plants grown at the four experimental sites (refer to the above) and berries on each peduncle were counted. A total of six harvests were made for each plant at each experimental site. Thus 120 peduncles were examined for each lantana cultivar in each experimental plot during a given harvest and 2,880 peduncles were examined across the four experimental sites through six harvests (20 peduncles per plant×2 plants within a block×3 blocks×4 sites×6 harvests) for each cultivar. An analysis of variance was conducted using the general linear model provided in SAS (PROC GLM; SAS Institute 2011) to compare the fruit production of ‘UF-T4’ with that of ‘Pink Caprice’.

‘Pink Caprice’ produced many more berries. Each peduncle of ‘Pink Caprice’ bore an average of 1.143 to 22.838 berries, with an overall average of 10.451 across the four sites and six harvests. The number of berries per peduncle on ‘Pink Caprice’ grown in Balm and Ft. Pierce ranged from 1.143 to 12.416, averaged to 6.783, while the number of berries per peduncle on plants grown in Quincy and Citra was 7.150 to 22.838, averaged to 14.118, more than 1-fold greater.

The number of berries ‘UF-T4’ produced per peduncle ranged from 0 to 0.358 and averaged to 0.023 across four experimental sites and over 6 months (Table 1). This level of fruit production represents greater than 99% reduction from the fruit production capacity of ‘Pink Caprice’. ‘UF-T4’ showed similarly low levels of fruit production regardless of whether they were planted purely (without L. depressa in Quincy and Citra) or interplanted with L. depressa (in Balm and Ft. Pierce).

Mature berries were collected from each plant in the above described experiments. Seeds were extracted, cleaned, and air-dried. Seeds were germinated in a 10.9-cm×10.9-cm transparent polystyrene germination boxes (Anchor Paper Company, St. Paul, Minn.) containing 2 sheets of germination paper (Anchor Paper Company) moistened with 15 mL of nanopure water. Germination boxes were placed in temperature and light-controlled chambers equipped with cool-white fluorescent lamps (Model 818; Precision Scientific, Winchester, Va.). The germination condition was 12 hours light at 25° C. (photosynthetic photon flux was 22 to 30 μmol m⁻² s⁻¹ at shelf level) followed by 12 hours dark at 15° C. Germination of seeds was monitored every other day for a period of 60 days. An additional 5-10 mL of nanopure water was added to the germination boxes as needed. A seed was considered germinated when radicle emergence was 2.0 mm or greater. Seeds were removed once germination occurred to prevent inaccurate data collection.

‘Pink Caprice’ seeds germinated readily, with an average germination percentage of 63.3, while ‘UF-T4’ seeds appeared abnormal and were likely not viable (Table 2).

Fruit (seed) production per peduncle and seed germination are the primary factors determining lantana's female fertility (or sterility). These two characteristics are factored into a female fertility index (FFI) by multiplying fruit production per peduncle and seed germination. The FFI for ‘UF-T4’ was 0 (Table 2), while ‘Pink Caprice’s FFI was 6.615. These results indicate an extremely high level of female sterility in ‘UF-T4’.

ASSESSMENT OF POLLEN STAINABILITY

Pollen stainability is a good indicator of lantana's male fertility (or sterility) and hybridization potential with Lantana depressa. Three pollen staining experiments were conducted using fresh anthers collected from the plants grown in Wimauma, Fla. on 24 September and again on 16 Nov. 2009 and from the plants grown in Ft. Pierce on 6 Oct. 2009. In each staining experiment, three inflorescences were collected per plant and three to four anthers were isolated from each of the inflorescences, resulting in eight to 12 anthers from any given plant and 48 to 72 anthers for each lantana cultivar (two plants per replicate and three replicates in each location). Collected anthers were placed in ˜100 μL of cotton blue solution (Eng Scientific, Inc. Product No. 6730, Clifton, N.J.) in a 1.5-mL Eppendorf tube and stained overnight at 65° C. Stained anthers were rinsed three times with deionized water, placed onto a microscope slide, squashed in a drop of 80% glycerol, and covered with a cover slip. Pollen grains were observed under 400× magnification on a BH-2 microscope (Olympus, Tokyo, Japan). Well developed, full and deeply stained pollen grains were counted as stainable, while non-stained, partially stained, or abnormally-shaped pollen grains were counted as non-stainable (aborted). The number of pollen grains examined for each lantana cultivar in each staining experiment was between 1,752 and 3,992. An analysis of variance was conducted using the general linear model provided in SAS (PROC GLM; SAS Institute 2011) to compare the pollen stainability of ‘UF-T4’ and ‘Pink Caprice’. The average pollen stainability of ‘UF-T4’ was 3.2% (Table 3). The average pollen stainability of ‘Pink Caprice’ was 65.6% (Table 3). These results indicate that the pollen stainability (or male fertility) of ‘UF-T4’ has been reduced by 95.1% from that of ‘Pink Caprice’.

ASSESSMENT OF HYBRIDIZATION POTENTIAL WITH Lantana depressa

Two hand pollination experiments were performed in the greenhouse in Wimauma, Fla., one in fall 2009 and one in spring 2010, to assess the ability of ‘UF-T4’ to cause fruit set on L. depressa flowers. Stock plants were grown in #1 plastic containers filled with a commercial soilless mix amended with a controlled release fertilizer (Osmocote,15N-3.9P-10K, 8-9 months release at 21° C.) at 7.12 kg·m⁻³. Temperatures inside the greenhouse ranged from a low of 16° C. at night to a high of 29° C. during day. No supplemental lighting was provided. Plants were drip-irrigated, twice a week as needed. Fresh anthers were collected from mature unopened flowers of ‘UF-T4’ and applied immediately to emasculated L. depressa flowers.

‘UF-T4’ did not cause any fruit set in the hand-pollination experiments (Table 4). ‘Pink Caprice’ effected an average of 8.9% fruit set. Seeds from L. depressa×‘Pink Caprice’ had 65% germination. These results confirm the high level of pollen infertility in ‘UF-T4’ compared to ‘Pink Caprice.’
